Need more detailed help to returning chromebook to stock state

HP Elite C1030
Currently running Windows11.

When i use MrChromeBox script to return to stock FW i receive the message that WP coulnd’t be enabled and maybe i should flash ChromeOS with removed battery.

Once ChromeOS is restored everything works fine except fingerprint reader - it’s listed as available hardware, but it doesn’t register fingerprints.

Here is a log from chrome://system/#HWID

And more thing, after successfully restoring ChromeOS with or w/o battery - WP in MrChromeBox script is always Green (disabled). I can flash again UEFI FW w/o disconnecting battery.

Need to restore FPR functionality.
